By helping most to understand the mode of the theme of asking for protection, different operating is described to a plurality of discrete wheel flow operations.Yet the order of description should not be understood that to hint that these operations must carry out in this order.Especially, these operations can not carried out in the order shown.The operation of describing can be carried out with the order of the execution mode that is different from description.In additional execution mode, various additional operations also can carry out, and/or the operation described also can be omitted.
This specification will use wording " in one embodiment " or " in a plurality of execution modes ", they each refer to one or more in the identical or different execution mode.In addition, as used in execution mode of the present disclosure, term " comprises ", " comprising ", " having " and similarly term be synonym.
As used herein term " module " can refer to, as a following part or comprise: the processor of application-specific integrated circuit (ASIC) (ASIC), electronic circuit, the one or more softwares of execution or firmware program (shared, special-purpose or group) and/or memory (shared, special-purpose or group), combinational logic circuit and/or described functional other suitable assemblies are provided.
Example embodiment is described at this combining wireless communication network, cordless communication network comprises such as comprising that any correction, renewal and/or modification ((are also referred to as LTE-Advanced (LTE-A) as LTE version 10, LTE version 11 etc.)) third generation partner program (3GPP) Long Term Evolution (LTE) network, global interoperability (WiMAX) network of inserting of microwave, and similar network.Execution mode described here can combining wireless electricity access network (the global terrestrial radio access network (E-UTRAN) of evolution that for example has the node base station (eNB) of evolution) and core net (evolution block core net that for example has gateway, management entity etc.) operate.
In other embodiments, communication plan described here can compatiblely be added/substituting communication standard, standard and/or agreement.For example, execution mode of the present disclosure can be applied to the wireless network of the other types that can obtain similar advantage.These networks can be including but not limited to wireless lan (wlan), Wireless Personal Network (WPAN) and/or wireless wide area network (WWAN), for example cellular network, and similar network.
The subsequent implementation mode can be used to comprise the transmitter and receiver of mobile wireless radio system in the multiple application.The radio system that is included in especially in the execution mode includes but not limited to network interface unit (NIC), network adapter, base station, access point (AP), via node, eNB, gateway, bridge, hub and satellite radio telephone.Further, radio system in the scope of execution mode can comprise that satellite system, PCS Personal Communications System (PCS), two-way radio system, global positioning system (GPS), bidirection pager, PC (PC) and relevant ancillary equipment, PDA(Personal Digital Assistant), individual calculate annex and all systems existing and that occur in the future, and it is correlated with in essence and the principle of execution mode can suitably be applied to.
Technology described here provides and makes that for example the subscriber equipment of M2M equipment (UE) can provide at least two priority-level (as the double priority level) for the communication of being initiated by UE in wireless network environment.In some wireless communications environments, M2M network over loading control work can be by being that single priority-level is simplified at running on that on the M2M equipment all use the M2M device-restrictive.This equipment will be assigned a priority-level, or " low priority ", or " normal priority ".In practice, a large amount of Machine Type communications be classified as " low priority " and therefore M2M equipment be assigned this setting.
Yet great majority use the M2M equipment of " low priority " also may have not frequently usually, a spot of occasion needs to use " normally " priority level initializing.For example, send daily report (as the per hour report of use amount) ammeter can with the report send as " low priority ".Yet, also may exist ammeter to wish to send with " normal priority " occasion of alarm, for example when this ammeter is distorted or be destroyed.
In another example, the pavement temperature transducer can send daily " I am still in work " communication by " low priority ", but, if pavement temperature is down to subzero, just may need to use immediately " normal priority " to send warning to control centre.
In another example, M2M equipment can a plurality of application of master control.For example, the room temperature that resides on the M2M equipment is used the data transmission that may require to use " low priority ", and the video stream application that resides on the same equipment may require to use the data of " normal priority " to transmit.Execution mode described here is not limited to above-mentioned example; Relating to above-mentioned example is for the technology that illustrates in the disclosure is set forth.
If equipment only uses in " low priority " or " normal priority " rank to communicate, really " low priority " equipment is set their M2M equipment use " low priority " the MTC user that need hinder of the support of a spot of " normal priority " event.On the contrary, MTC user will be encouraged to dispose for " normal priority " rank at the equipment of communication any time with them.This will cause the undesired consequences relevant with extra network over loading.
Embodiments of the present invention provide the application that can reside on the M2M equipment, and it has in the ability of using acquiescence " low priority " setting that surmounts (override) this equipment under the situation that may need transmission " normal priority " communication.
In one embodiment, UE and/or the communication (as the request of being initiated by the application of UE master control) initiated by UE can be assigned acquiescence (as low) priority-level.In some cases, for example under other situations of describing in detail promptly and subsequently, UE can be configured to surmount the default priority relevant with the request of initiating and distribute higher (as " normally ") priority to the request of initiating, and this request will be handled by the priority-level of network based appointment.For example, network may be congested and can not accept request or other communication from the UE relevant with default priority (or low-level priority) immediately, but can accept and handle request or other communication from the UE relevant with higher priority (normally), this priority can be assigned to this communication by UE.More particularly, therefore if network is confirmed as congested and can not handles the request with acquiescence (low) priority from UE, this network can provide latency value to UE, and UE is limited to attempt this network of liaison by having low priority during the waiting time value.Yet if UE uses higher (normally) priority-level to initiate request, these requests will allow to be accepted by network.
In another embodiment, may wish that UE has the ability that surmounts the access control configuration relevant with UE, for example restrict access of expansion configuration.The restrict access (EAB) of expansion is the mobile mechanism of initiating access attempts of operator (one or more) UE that has been used for controlling self-configuring EAB, to prevent Access Network and/or core net overload.Under congested or overload situations, the operator can limit self-configuring EAB UE access but allow access from other UE.The UE that has disposed EAB is considered to can tolerate the access restriction more than other UE.When the operator determined to need to use EAB, the information of Web broadcast necessity was to provide EAB control to the UE that is in the specific region.
Yet, in some cases, need surmount the restrict access configuration of expansion, surmount ability in conjunction with above-mentioned low priority typically.This will be referred to a fact, and configuration is also disposed for EAB for the UE of low access priority usually.Correspondingly, in the time low priority must being surmounted for the communication of being initiated by UE, also the carrying out that EAB sets to allow this communication might must be surmounted.Under different situations, be configured to provide the operation of the UE of double priority level after this being described in detail at the communication of being initiated by UE.
Fig. 1 exemplarily illustrates the example wireless network 100 according to some execution modes.Network 100 can comprise RAN20 and core net 25.In some embodiments, network 100 can be the LTE network, and RAN20 can be E-UTRAN, and core net 25 can be evolved packet system (EPS) type core net.UE15 can be by the eNB among the RAN20, and for example among the eNB40,42 etc. inserts core net 25 via radio link (" link ").UE15 for example is configured to follow the subscriber station (as M2M equipment) that one or more agreements are communicated by letter with eNB40,42.For convenience of description, follow-up explanation provides the network 100 of following 3GPP as example; Yet theme of the present disclosure is not limited to this respect, and the execution mode of describing can be applied to other networks that can benefit from principle described here.In some embodiments, UE15 can be configured to use multiple-input and multiple-output (MIMO) communication plan to communicate.One or more antennas of UE15 can be used to use concomitantly the radio resource of a plurality of corresponding component carrier (as corresponding to eNB40,42 antenna) of RAN20.In some embodiments, UE15 can be configured to for example using OFDM (OFDMA) in the downlink communication, and/or is for example using single-carrier frequency division multiple access (SC-FDMA) in the uplink communication.
Although it is mobile device (as cell phone) that Fig. 1 shows UE15 in general manner, UE15 can be PC (PC), notebook, super, net book, smart phone, super mobile PC (UMPC), handheld mobile device, Universal Integrated Circuit Card (UICC), PDA(Personal Digital Assistant), ustomer premises access equipment (CPE), board in different execution modes, or other consumption electronic products, for example MP3 player, digital camera, and similar equipment.As mentioned above, UE15 can be Machine Type communication (MTC) equipment, is also referred to as M2M equipment.In the disclosure, purpose for simplicity, term " UE " and " equipment " will exchange use.ENB40,42 can comprise one or more antennas, be used for modulation and/or demodulation one or more radio modules of signal that launch or that receive on the interface aloft, and for the treatment of one or more digital modules of signal that launch or that receive on the interface aloft.
In some embodiments, can promote communicating by letter via RAN20 and UE15 by one or more nodes 45 (as radio network controller).These one or more nodes 45 can be used as the interface between core net 25 and the RAN20.According to different execution modes, these one or more nodes 45 can comprise be configured to management of base station 40,42 and core net 25 (as one or more servers 50) between the mobile management entity (MME) of signaling exchange (as the authentication of UE15), be provided to the grouped data network gateway (PGW) of the gateway router of the Internet 65, and/or the management RAN20 eNB40,42 and PGW between the user data tunnel or the gateway (SGW) in path.Also can use the node of other types in other embodiments.
The logic (as module) that provides the authentication of UE15 or other actions relevant with the foundation of communication link can be provided core net 25, so that the connection status of UE15 and network 100 to be provided.For example, core net 25 can comprise and can be coupled to base station 40, one or more servers 50 of 42 communicatedly.In one embodiment, these one or more servers 50 can comprise home subscriber server (HSS), and it can be used for the customer parameter of management such as user's international mobile subscriber identity (IMSI), authentication information etc.Core net 25 can comprise other servers, interface and module.In some embodiments, the logic relevant with the different functionalities of one or more servers 50 can be combined to reduce the quantity of server, for example comprises being incorporated in individual machine or the module.
According to various execution modes, network 100 can be based on the network of Internet protocol (IP).For example, core net 25 can be or the network of at least part of IP of being based on for example packet switching (PS) network.Interface between network node (as one or more nodes 45) can be based on IP's, is included in base station 40,42 backhaul connects.In some embodiments, can make network 100 can be provided to the connection of circuit switching (CS) network (as the CS territory).In one embodiment, UE15 can communicate by letter with network 100 according to one or more communication protocols, for example is applicable to radio resource control (RRC) agreement of LTE communication environment.
Fig. 2 shows the example connection layout between UE15 and the network 100.Shown in Figure 200, UE15 can send RRC connection request message 204 to network controller 206.This RRC connection request message 204 can be the request of the radio resources allocation of UE15, thus UE15 can with the RAN20 swap data.Network controller 206 can be controlled RRC establishment of connection and/or the maintenance between UE15 and the RAN20.Network controller 206 can be positioned over UE15 to be attempted to set up among the eNB40 or 42 that RRC is connected with it.In other embodiments, network controller 206 or its assembly can be placed in additional/interchangeable network entity, as in the node of one or more nodes 45, in the server of one or more servers 50 etc.
If RAN20 is in congestion state and can not support the RRC relevant with RRC connection request 204 to connect, network controller 206 will respond to refuse RRC connection request message 204 with RRC connection refused message 208.In this case, UE15 is not connected and can be established with RRC between the RAN20.In an example, RRC connection request message can relate to the NAS request message, for example attach request, tracking area update request or expansion service request.
In some cases, for the equipment of particular type, as MTC equipment, network controller 206 provides stand-by period (WT) value in connection refused message 208, and it is also referred to as expansion stand-by period or EWT.During the stand-by period, bring into operation and maintenance equipment " hang-up (on hold) " with the timer (being called as " keeping out of the way timer ") of device association, namely prevent and send communications to network, expired up to the stand-by period, this equipment will be allowed to transmit a request to again network.
Latency value can be provided for equipment (UE) in other cases.Fig. 3 illustrates UE15 by sending RRC connection request message 304 is initiated the situation of connection request to network controller 206 block diagram 300.Network controller 206 can determine that RAN20 can support the RRC relevant with RRC connection request message 304 to connect in this case.Correspondingly, network controller 206 can be set up message 308 responses with connection.According to the communication protocol that adopts, can between UE15 and network controller 206, send a plurality of other handshake information (not shown).For example, UE15 can set up completed notice to respond connection with connection and set up message 308; Network controller 206 can send safe mode and set up order; But UE15 informing network controller 206 safe modes are set up.In one embodiment, network controller 206 can provide the RRC connection release message 310 that can comprise latency value.In brief, when network congestion or overload, network controller 206 can be specified the expansion stand-by period and be required UE15 " to keep out of the way " during the stand-by period.Next will illustrate when network congestion and UE15 received latency value in response to request (as connection request) from network, how the UE15 that configuration is used for the double priority level handled.
Fig. 4 is the process flow diagram of communicating by letter that illustrates according between network controller in the wireless network environment of execution mode (as network controller 206) and the UE (as UE15).Suppose that UE is configured to double priority level equipment.For example, UE can be configured to provide surmount in some cases with equipment or with residing in one or more application on this equipment the ability of relevant low priority.(be understandable that " double priority level " can mean two or more priority in context of the present disclosure.The example of two priority only provides with the purpose that lays down a definition.)
Process 400 starts from piece 402, and wherein UE can send request (as connection request) to network controller.As mentioned above, mobile device may be initiated dissimilar communication, for example the RRC connection request.As described with reference to figure 2, if network congested is on a certain intended level that is connected that allows to set up with this equipment, network controller can be with the refuse information that has latency value (for example, network controller can send above-mentioned RRC connection refused message) in response, shown in piece 404.In piece 408, the latency value of reception is used to start keeps out of the way timer, and this is kept out of the way timer and determines that this equipment is limited to send to network controller the time period of another request.At piece 410, the priority value relevant with the request of this equipment (as acquiescence (low) priority or normal priority) can be by this device storage in order to using in the future.
Fig. 5 is the process flow diagram that is used for being handled by the subscriber equipment of for example UE15 at wireless network environment the communication of double priority level according to some execution modes.Process 500 starts from piece 502, and wherein UE can receive to provide and surmount with this UE and/or reside in the configuration of the ability of relevant acquiescence (as the low) priority of application on this UE.For example, new configuration parameter can be added in the UE configuration that can surmount default priority.More particularly, new configuration parameter can be added in Non-Access Stratum (NAS) configuration of UE, and this NAS configuration allows to surmount NAS low priority designator and sets.In another example, as mentioned above, new configuration parameter can be added in the Non-Access Stratum configuration of the access limitation arrangement that allows to surmount expansion.This configuration parameter can be provided by the work supplier of cordless communication network at place of UE.As mentioned above, this cordless communication network can comprise for example UTRAN or E-UTRAN.
At piece 504, can be initiated by UE such as the communication to the request message of network controller (as network controller 206).For example, the application that resides on the UE can be indicated and need be sent request to network controller.As mentioned above, can be the request of any type to the request of network controller, RRC connection request for example.In other examples, UE can initiate the request relevant with attach procedures (this UE " attached " being arrived this network as request), tracking area update program, position refresh routine, routing region updating program, service request program and analog to network controller.In another example, application can be initiated request (for example asking to send information via network to the terminal use).
At decision block 506, determine whether the application of initiation communication is relevant with the priority-level that is different from default priority.For example, determine whether application is relevant with normal priority.If this of determine initiating communication used not relevant with priority except default priority, process 500 advances to decision block 508.Otherwise process 500 advances to piece 512.
At decision block 508, determine whether require to surmount default priority from the communication of this application.As mentioned above, typically the request that and transmission relevant with acquiescence (low) priority is relevant with acquiescence (low) priority or other some application of communicating by letter can need to send the communication relevant with higher priority once in a while.For example, ammeter may wish to send alarm with " normal priority ", if for example this ammeter is being distorted or just destroyed, in contrast, daily report sends with low priority usually.
Do not surmount default priority if this communication of determining requires, at piece 510, this communication is initiated (for example sending) with the default priority indication and is handled according to the priority of indication to controller and by network controller.
If determine that this communicating requirement surmounts acquiescence (for example low) priority, process 500 advances to piece 512, and wherein this low priority is surmounted, and for example uses reference block 502 described configurations to set.At piece 514, this communication is initiated (for example sending) to controller by the priority (for example normal priority) with different stage, and the priority of this different stage is allowed by the double priority level feature of UE configuration.
Fig. 6 is the process flow diagram that is used for being handled by subscriber equipment at congested wireless network environment the communication of double priority level according to some execution modes.As described with reference to figure 4, under congested network condition, network controller use refuse information responds the communication (connecting as request) from UE, and this refuse information comprises the latency value that guiding UE restriction is exceeded the time limit up to the stand-by period to network transmission communication.UE can utilize the latency value of reception to start to keep out of the way timer, and storage and this UE that has triggered the refusal that comes automatic network relevant priority value of communicating by letter morning.
In some cases, the latency value of reception can be ignored by UE.Yet, for the purpose of execution mode shown in Figure 6, suppose that UE can not ignore the latency value of reception.
Process 600 starts from piece 602, and wherein UE is configured with to provide and surmounts with this UE and/or reside in the configuration of the ability of relevant acquiescence (as the low) priority of application on this UE, is similar to above with reference to figure 5 described examples.At piece 604, can be initiated by UE to the communication of network controller.As described with reference to figure 5, communication can relate to connection (connecting as PDN) or other mobile management functions (as attach procedures, tracking area update program, position refresh routine, routing region updating program, service request program etc.).At decision block 606, can determine relevant with this UE keep out of the way timer and whether move.Do not move if determine to keep out of the way timer, process advances to piece 614, and wherein the communication of Fa Qiing will be sent to network controller.
Move if determine to keep out of the way timer, at decision block 608, determine whether this keep out of the way timer because the communication formerly relevant with acquiescence (as low) priority (as the response to the communication of UE transmission) and be activated.For example, keeping out of the way timer may start owing to formerly mobile management function, and the mobile management function is for example such as the NAS request message of the service request of attach request, tracking area update request or expansion.As described with reference to figure 4 (piece 410), when keeping out of the way timer and start, the priority value (low or normal) relevant with having triggered the communication of keeping out of the way timer will be stored.Correspondingly, at decision block 608, determined to trigger the priority-level of the communication of keeping out of the way timer.If determine that this startup of keeping out of the way timer is relevant with the communication with the priority-level (as normal priority) that is different from default priority, process 600 advances to piece 616, wherein only when keeping out of the way timer and exceed the time limit the communication of this initiation just can be sent out.
If determine that this startup of keeping out of the way timer is relevant with the communication with low priority level (as the request message of NAS formerly with low priority level), at decision block 610, determine whether the communication of initiating is relevant with the priority that is different from default priority (as normal priority).Some examples of request that can be relevant with normal priority had before been described with reference to figure 5 (piece 508).If the communication of determine initiating is not relevant with the priority that is different from acquiescence (as low) priority, then process 600 advances to piece 616, wherein only when keeping out of the way timer and exceed the time limit the communication of this initiation just can be sent out.If determine that the communication of initiating is relevant with the priority that is different from acquiescence (as low) priority, can surmount UE acquiescence (low) priority at piece 612.At piece 614, the communication of initiation uses the priority that is different from acquiescence (as normal) priority to send, and the low priority of this priority ratio acquiescence is higher.
Different execution modes can comprise that more following influence to the core technology standard is to allow supporting multipriority to use/configuration.These influences can realize for example UE configuration, attach request, band of position renewal (LAU)/routing region updating (the RAU)/processing of tracking area update (TAU), the processing of congestion management, EPS session management (ESM) setting, and EAB sets.
For the UE configuration, UE can continue to have the NAS signaling low priority configuration according to NAS_SignalingPriority leaf (leaf) in supporting the NAS configuration MO of low priority applications.Yet UE may need can be for other non-low priority applications surmount this configuration, thereby low priority is not included in NAS message (be different from for emergency services and be used for those of access grade 11-15).Because UE also can support other non-low priority applications, can dispose MO to NAS and add additional config option to specify this UE to have to surmount the ability of low priority designator.
For attach request, if in existing standard because network congestion or overload situations make attach request be rejected, UE can start keep out of the way timer and when this is kept out of the way timer and is moving UE should not initiate another attach request.In the present embodiment, this behavior will change for non-low priority applications.UE can be allowed to surmount network congestion and be that non-low priority applications is initiated attach request by the low priority designator for example set suitably among the device attribute IE in the NAS message.
For the processing of LAU/RAU/TAU, if if network congestion and UE are moving and keep out of the way timer in existing standard, then the LAU/RAU/TAU program can not initiated, and keeps out of the way timer up to this and exceeds the time limit or stop.Yet, if UE can complete successfully attach request for non-low priority applications, and if should connect the maintenance activation, then as long as any EPS bearer context activates, UE should be allowed to initiate the LAU/RAU/TAU program, namely is used in keeping out of the way timer and may moving of low priority applications.
For the processing of congestion management, low priority applications should not have influence congested and the overload management.Yet, in some cases, may not have the NAS message of low priority designator can be rejected and UE can be required to start and keeps out of the way timer yet.UE can wish to keep out of the way the singleton of timer for different application (low priority and other non-low priority applications) maintenance in this case.In this case, program and the policy for low priority applications also can be applied to other non-low priority applications.
Set for ESM, the ESM of device attribute sets and can be set up based on the priority of the application of using PDN to connect by UE, and for example UE can set the device attribute of ESM message based on the PDN connection priority.In some embodiments, UE can the managing conversation management keep out of the way timer on each PDN connection basis, rather than on entire equipment/UE basis.For example, UE can keep out of the way timer for each the control session management in a plurality of PDN connections.In other embodiments, the individual session managing timer can be used to control a plurality of PDN connections.Process based on the application settings device attribute of moving may need to revise.Further, the session management program may need to revise to reflect this situation.
Configuration can be by comprising that in suitable NAS message device attribute IE indicates this point for the UE of NAS signaling low priority, wherein the low priority designator is set to " MS is arranged to NAS signaling low priority ", except in some cases, UE can be set to " MS is not arranged to NAS signaling low priority " by the low priority designator.Different execution modes provides these situations to include but not limited to work as the UE that the support of double priority level is provided and is configured to surmount NAS signaling low priority designator: using the low priority designator that is set to " MS is not arranged to NAS signaling low priority " to set up PDN and connecting; Carrying out with use the EPS session management program of the PDN join dependency of the low priority designator foundation that is set to " MS is not arranged to NAS signaling low priority "; And/or have the PDN connection of using the low priority designator foundation that is set to " MS is not arranged to NAS signaling low priority " and carrying out EPS mobile management program.Be understandable that " use is set to the low priority designator of ' MS is not arranged to NAS signaling low priority ' and sets up the PDN connection " can be understood that to mean that the one or more NAS message be used to setting up the PDN connection have the deviceelement IE that the low priority designator is configured to indication " MS is not arranged to NAS signaling low priority ".Similarly, one or more NAS message of be used for carrying out EPS session management program and/or carrying out EPS mobile management program can allow their the low priority designator of deviceelement IE by similar setting.
